1_1000_GAIN_RANGE

Published:2009/7/6 6:39:00 Author:May | From:SeekIC

Control voltage of 0 to -9 V changes gain of amplifier over complete range while providing maximum output level of 8.5 VRMS and bandwidth of over 20 kHz at maximum gain. If gain range of 100 is sufficient, amplifier can be changed to LM30lA; 20K resistor is then changed to 2K.- Linear Applications, Vol. 2, National Semiconductor, Santa Clara, CA, 1976, AN-129, p 5.
